Introduction: Hide-A-Key

An easy way to keep a spare key on the outside of a vehicle.

Materials:

Spare Key (preferably with Key Ring)
Strong Magnet (old hard drive magnets are ideal)
Electrical Tape

Step 1: Thread Key on to Magnet

Put the key ring through the hole on the magnet.

Step 2: Wrap With Electrical Tape

Get the key flat against the magnet and wrap with electrical tape. This is to prevent the key from flapping around, and also to protect the bumps and ridges of the key from dirt and wear.

Step 3: Stick It to Your Car

Put the key and magnet somewhere on the under carriage of your car. I tend to stick mine somewhere around the rear bumper.

Never get locked out of your car again!

    Oh.. I see :0) I lose everything! Where do you think discarded computers might be and more specifically, do you have any ideas where I could find the magnet without tearing apart a computer?

    While hard drive magnets are stupid strong, you can get very strong rare-earth magnets (they're plated silver color) at Radio Shack or similar.

    its probably a good idea to separate identification and keys, so that if one gets lost/stolen, the finder/stealer does not have easy access to your dwelling (exact location, and keys)

    I do the same thing Nano. But my address on my ID's is from a few years ago and halfway across town from where I really live. lol

    You can get coded tags for stuff at travel stores. You register at the website and if someone finds your stuff (not just keys) they call the number on the tag and they tell them what to do with it. Got one on my keyring.

    i love that its a hard drive magnet.. but i have a store-bought hide-a-key on my car... in a difficult place to find. difficult enough that i thought I lost it on the road somewhere until I looked again a couple months later!

    I'm here to post my official disapproval of your choice of tape. After one hot day, your key is going to be covered in goo. I'd suggest masking tape! :)

    I would not use any type of tape... My preference would lean towards shrink tubing the key onto the magnet.

    i was thinking the same thing, but that could make it difficult to remove (since if you lost your keys you may have lost your knife), and gunk will accumulate inside of the heat shrink. i think a pop rivet through the fob and magnet will hold things pretty well, whiel still allowign use of the key and the brass of the key is reasonably non reactive, and unless it's getting battered by gravel in your wheel well, it should be ok on it's own. maybe a wrap or two of saran wrap over the entire thing.

    Simple solution: Jewelry or bead baggie (The little ones that look like they're for dope). Put the whole thing into the baggy, then wrap the baggy in just one or two loops of tape to make it tight. No goop on key, and still reasonable to open.

    True. I'm not saying put a florescent green baggie under your car. What I mean is that most thieves now to look for spare keys under the car. If they see a baggie wrapped in tape, that is an obvious sign.

    Read the instructable again. And look at the pics. The key is connected to the magnet with a steel split ring. The tape is only there "to prevent the key from flapping around." Actually, you could just wrap the thing with a few tight turns of saran wrap and call it good.

    Some concern about new car keys with chip in them. What is effect of strong magnet?
